The upcoming JSP technology Hans is referring to is called JavaServer Faces
(not JavaFaces). What little information is available can be found at:
http://jcp.org/jsr/detail/127.jsp.
Also, I noticed in a press release about Web Services Pack
(http://java.sun.com/pr/2001/06/pr010604-03.html), it states the following:
"Web Services Pack is a collection of application programming interfaces
(APIs) and architectures developed by Sun and the other members of the Java
Community that provide support in the Java technology for important web
services features. Current plans call for the Web Services Pack to include:
JavaServerTM Faces, which is under development in the Java Community
ProcessSM Program, establishes a standard API for creating Java Web
application graphical user interfaces (GUIs), eliminating the burden on
developers to create and maintain the GUI infrastructure from scratch."
Notice the reference to JSF. It seems to me that this is a critical piece
for Sun to be able to effectively compete against the Microsoft Web Form
Controls. But, according to Amy Fowler from Sun, the expert group is
currently working on the community draft of the JSF specification, and will
hopefully be completed towards the end of the year.
Interestingly, Qbizm Technologies (http://www.qbizm.com/) has a product,
HyperQbs, which is supposed to be based on this yet non-public
specification. So, if you want to get an idea of what will be possible,
check them out.
